" On my search Zero has 180 employees and this recall is for 218 units. Maybe they should give a bonus this year and let every employee grab a free bike! "

" As I was riding around today on my Zero, a thought occurred to me. I wonder what will happen to all of the motors, Sevcon controllers, contactor switches, frames, wheels, brakes and other expensive chassis and electronic parts on those 2012 Zeros after the batteries are removed and recycled? I hope they are put back on the market for DIY use, instead of being tossed into the dumpster because that is what will make liability lawyers happy. "

" EV200 or LEV200? It was my understanding the LEV is the non economizer version.
Either way, yes I will have a suitable contactor installed other than my keyswitched one as soon as possible.
The motor is hooked up to the bike and at this point I have most of the settings how I want them. The only issue is that any more than a hair of throttle and it will continue to run away accelerate even when throttle is reduced with fwd and Foot switch disconnected.
I Imagine that one of the gains somewhere has to be off. I'll keep digging. 2 hours every night and eventually i'll crack it.
Thanks "

" The controller is set for torque mode, so throttle percent = torque percent. The RPM can very easily spin out of control if there's no load on the motor. Once it's installed in a vehicle, it'll feel more like the original ICE. I think you're expecting it to operate in Speed mode, where throttle percent = motor RPM percent.

Not sure what contactor you got, but do NOT use an EV200. They don't work properly with the Sevcon.

Don't operate without having the sevcon control the contactor. I just don't recommend it. It's OK for now, but the sevcon cannot disconnect itself if there's a fault. Just interrupt power to KSI if you want to turn off/on the controller. "

" Well I ordered a new contactor and I was able to get it spinning by setting contactors to 0 and setting it to ignoring contactor welded faults. Then Turn on -> connect FWD -> and then it goes whenever FS1(throttle switch) is on and the throttle input is above min.
Only issue I have now is that the bike accelerates to runaway and I have to slam the E stop to stop it from taking off. A tiny amount of throttle seems OK. Anymore and It just takes off! Maybe because FS1 turns off?
I guess I need to look and see if the throttle is mapped to something crazy.

Getting closer :-) I am super excited for the torque. "

" This is kind of a common question, and I went through some posts here to try to find a good thread about it, but came up empty. Anyway, the short answer is it's not really worth it. The general conclusion is it's better just to put the space, money and effort into a nice high-discharge pack. A few years ago that was what we fondly refer to as RC lipo, but now there are several chemistries that can deliver the power.

That said, nobody I remember hearing about has actually done it. (...as my son would say, "is that a challenge?" lol)

" The Sevcon should be the only thing connected to the contactor. The Sevcon controls it. You just need to give pack voltage to pin 1, KSI.

Wire per the manual.

Next, FS1 needs to be active prior to activating forward, and before giving throttle. Needs to be in that order. "

" Hi all,
I got my new sevcon, Thanks Travis!, but I need some help with the fault codes.(I tired searching the forum first)
I am converting from a Kelly so the setup is a little odd.
Basically I have my battery ground on a E stop(with high current auto disconnect) this connects everything including my dc/dc converter.
My key switch switches 12V from the DC to the contactor which then connects the 96V pack to the B+ on the sevcon and the logic circuit.

So first issue: do I need to have my contactor tied to the Sevcon to work? Can I just select 0 contactor inputs and have them all "not specified"
If I have it set to 1 I get a line contactor welded fault. Otherwise I don't get a fault. Alternately I tried to tie a dummy 12V relay to the contactor line and still would get the fault (contactor voltage set to 12V)

Second Fault: I get a sequence fault: I am assuming that I have an issue with my FS1 or FWD switch inputs. I have FS1 tied to the throttle switch and FWD tied low. REV is left floating. Am I missing an input required for the sequence?
I cannot seem to find much detailed info on what the sequence is.... Very "PC load letter" to me.

Thanks all and hopefully this helps someone else in the future too. "

" Hello everyone,
My name is john. I am from montreal, canada. I need a question answered concerning an idea i have concerning ev power.
Would it be feasable to power an electric motor solely with super capacitors to provide a say... 30kw boost to a motorcycle?? Power would be on or off, like a hit of nitrous. The power would not need to last more than 5-10 seconds. I know capacitors recharge relatively quickly so the motor can do regen on off throttle mode. This would also help stop the motorcycle.
Do you guys think this idea is sensible, or perhaps know if anyone has invented such a system?
Im no electrical wiz, i just think it would be a cool way to boost a conventional motorcycle.
My email is: jp1234554321@gmail.com
Feel free to contact me directly if you like. Thanks for taking the time to read this. -JOHN "

Im in st. Eustache. The build will be more focused once my front end is finished being built. I have respected the dimensions and parameters we have to adhere to with the quebec vehicle law. Once the project becomes a rolling chassis, then footpeg placement, seat height and handlebar placement will decide the rest. "
